Safety instructions for operation
Hazardous voltages at the machine
Electrical machines have hazardous voltage levels. Contact with these can result in death,
serious injury or material damage.
Operating the machine on a line supply system with a non-grounded neutral point is only
permissible for short periods of time that occur rarely, e.g. the time leading to a fault being
eliminated. Cable ground fault EN / IEC 60034-1.
Risk of injury due to rotating parts
Rotating parts are dangerous. Touch protection against rotating parts is no longer guaranteed
if covers are removed. Touching rotating parts can cause sparking with subsequent ignition of
an explosive atmosphere resulting in death, serious injury or material damage.
• Carefully ensure that all of the covers are closed while operational.
• First switch off and disconnect the machine if you must remove covers. Carefully comply with
the "5 safety rules (Page 15)".
• Only remove the covers when the rotating parts have come to a complete standstill.
Danger as a result of stationary parts under voltage (live parts)
Live parts represent a hazard. Touch protection against active (live) parts is no longer
guaranteed if covers are removed. The minimum air and creepage distances may be fallen below
(violated) when coming close to active parts. Touching or coming close can result in death,
serious injury or material damage.
• Carefully ensure that all of the covers are closed while operational.
• First switch off and disconnect the machine if you must remove covers. Carefully comply with
the "5 safety rules" (Page 15).
• In operation, the terminal box must always be kept closed. It is only permissible to open the
terminal box when the motor is stationary and in a no voltage condition.
